t" 1 claim. (ci. 15s-4) This invention relates to an apparatus forbustion promoting air, as shown, this construcburning corrosive liquidsand fluids of the type tion having the advantage of supplying only Dreofacid sludge in a manner which will avoid con'- heated air forfacilitating the combustion of the tact of the unconsumed sludge withany parts of iluids introduced.

One of the main objects of the invention is to The burner includes anozzle I0 connected with provide a burner for supplying acurtain ofsteam a steam supply pipe I2 leading to a suitable onto which thecorrosive fluids are discharged, source of supply controlled by thevalve I5. The

Since the sludgenozzle I6 is entirely distinct from and separated from the steam nozzlel0, there is no contact of the sludge with the steam nozzle and nocontact with any metal parts after the steam and sludge are brought intocontact. 'Ihe burner has been found eclent in operation andsubstantially free from deterioration produced by'the corrosivecharacter of the sludge.

While reference is made herein to a particular material to be consumed,it will be understood that the invention is not'so limited and that theapparatus is useful for disposing of any other similarly corrosivefluids.

Obviously many modifications and variations of the invention, ashereinbefore set forth, may be made without departing from the spiritand scope thereof, and therefore only such limitations should be imposedas are indicated in the appended claim. A

I claim:

In a furnace formed with a fire box for burning corrosive liquids, asteam nozzle constructed to provide a. fan-shaped jet of steam in saidfire box, a liquid discharge nozzle positioned adjacent but out ofcontact with said rst-named nozzle for discharging corrosive liquids ina fanshaped stream upon said `iet of steam and a burner for fluid fuelpositioned beneath said nozzles and adjacent the same for facilitatingthe combustion of said corrosive liquids.
